For U.S. adults, quality-adjusted life expectancy increased by about two years from 1987 to 2008
MONDAY, Sept. 16 (HealthDay News) -- Health surveys show that quality-adjusted life expectancy has increased by about two years in U.S. adults over the past 20 years, according to research published online Sept. 12 in the American Journal of Public Health.
Susan T. Stewart, Ph.D., of the National Bureau of Economic Research in Cambridge, Mass., and colleagues used data from national surveys on health, medical expenditures, and mortality to estimate trends in quality-adjusted life expectancy from 1987 to 2008.
The researchers found that, although increases in obesity and some health symptoms and impairments slowed improvement, years of quality-adjusted life expectancy increased overall and for all demographic groups, including men and women and blacks and whites. Adults aged 25 years gained 2.4 years and adults aged 65 years gained 1.7 years of quality-adjusted life expectancy.
"We found that quality-adjusted life expectancy has increased over the past two decades, driven by improvements in life expectancy and reductions in the prevalence of several symptoms and impairments, most notably low energy, depressive mood, pain, self-care, routine needs, and, prior to 2000, anxiety and vision problems," the authors write.
